Description
本發明是有關於一種物品搬送台車，其包括沿著行走路徑行走的台車本體、從下方支撐物品的底面的支撐部，及使前述支撐部沿著水平方向，在使其朝向相對於前述台車本體位於橫側方之移載目的地突出的突出位置，及使其從該突出位置退回到前述台車本體側的退回位置之間進退移動的進退用驅動部。 The present invention relates to an article transporting cart including a bogie body that travels along a traveling path, a support portion that supports a bottom surface of the article from below, and the support portion is oriented in a horizontal direction with respect to the bogie body A protruding position that protrudes from the transfer destination on the lateral side, and a forward/backward drive unit that moves back and forth between the retracted positions on the side of the bogie body from the protruding position.
如上述的物品搬送台車之一例，已記載於特開平6-321316號公報(專利文獻1)。在專利文獻1的物品搬送台車中，於將物品搬送至移載目的地的情況，是在支撐部支撐著物品的狀態下，使台車本體行走至對應於移載目的地的停止位置之後，藉由進退用驅動部使支撐部於突出位置及退回位置之間進行進退移動，而將物品搬送至移載目的地。又，於從移載目的地搬送物品的情況，是在支撐部未支撐物品的狀態下，使台車本體行走至對應於移載目的地的停止位置之後，藉由進退用驅動部使支撐部於突出位置及退回位置之間進行進退移動，而從移載目的地接收物品。之 後，在以支撐部支撐著物品的狀態下，使台車本體從停止位置開始行走。 An example of the above-described article transporting vehicle is disclosed in Japanese Laid-Open Patent Publication No. Hei 6-321316 (Patent Document 1). In the article transporting trolley of the patent document 1, when the article is transported to the transfer destination, the trolley body is moved to the stop position corresponding to the transfer destination while the support portion supports the article. The forward/backward driving unit moves the support portion forward and backward between the protruding position and the retracted position to transport the article to the transfer destination. In the case where the article is transported from the transfer destination, the support body is driven by the forward/reverse drive unit after the carriage body has traveled to the stop position corresponding to the transfer destination while the support portion is not supporting the article. The forward and backward movement is performed between the protruding position and the retracted position, and the item is received from the transfer destination. It Thereafter, the trolley body is caused to travel from the stop position in a state where the article is supported by the support portion.
在專利文獻1的物品搬送台車中，由於支撐部所支撐的物品，只是以支撐部從下方支撐著該物品的底面，所以會有例如，在台車本體行走於行走軌道的段差時或加速及減速時等發生物品上拋脫離支撐部或傾倒之疑慮。並且，即便是在使物品與支撐部沿上下方向相互嵌合以防止物品掉落的情況下，仍有因物品的上拋或傾倒導致該嵌合脫落而使物品從支撐部掉落之疑慮，或者在物品是由複數個貨物所構成的情況中，會有因物品的上拋或傾倒而導致該貨物倒塌之疑慮。 In the article transporting trolley of the patent document 1, the article supported by the support portion only supports the bottom surface of the article from below by the support portion, and therefore, for example, when the trolley body travels on a step of the traveling rail or accelerates and decelerates When the item is thrown off the support or dumped. Further, even when the article and the support portion are fitted to each other in the vertical direction to prevent the article from falling, there is a fear that the article is detached from the support portion due to the falling or pouring of the article, and the article is dropped from the support portion. Or in the case where the article is composed of a plurality of goods, there is a concern that the goods may be collapsed due to the falling or dumping of the articles.
於是，所要求的物品搬送台車為，於在退回位置與突出位置之間進退的支撐部上支撐著物品的狀態下，使台車本體行走時，可以藉由支撐部以穩定的狀態支撐物品。 Then, the required article transporting carriage is such that, in a state in which the article is supported by the support portion that advances and retreats between the retracted position and the projected position, when the trolley body is moved, the article can be supported by the support portion in a stable state.
本發明的物品搬送台車，具備以下設備：台車本體，沿著行走路徑行走；支撐部，從下方支撐物品的底面；進退用驅動部，使前述支撐部沿著水平方向，在使其朝向相對於前述台車本體位於橫側方之移載目的地突出的 突出位置，及使其從該突出位置退回到前述台車本體側的退回位置之間進退移動；按壓部，位於前述退回位置的前述支撐部所支撐的物品的正上方；間隔切換用驅動部，對作為前述支撐部及前述按壓部的上下方向上的間隔的對象間隔進行切換；在此，前述間隔切換用驅動部是可將前述對象間隔切換成使前述退回位置的前述支撐部及前述按壓部在上下方向接近，而使前述按壓部從上方按壓前述支撐部所支撐的物品的按壓間隔，並且可將前述對象間隔切換成使前述退回位置的前述支撐部及前述按壓部在上下方向分開，而容許前述支撐部的進退移動的分開間隔。 The article transporting trolley of the present invention includes: a trolley body that travels along a traveling path; a support portion that supports a bottom surface of the article from below; and a drive portion for advancing and retracting, the support portion is oriented in a horizontal direction with respect to The aforementioned trolley body is located at the transfer destination of the lateral side a protruding position and moving forward and backward between the retracted position of the bogie body side returning from the protruding position; the pressing portion is located directly above the article supported by the support portion at the retracted position; and the interval switching driving portion is The distance between the support portion and the pressing portion in the vertical direction is switched. The interval switching drive unit is configured to switch the target interval to the support portion and the pressing portion at the retracted position. When the up-and-down direction is close, the pressing portion presses the pressing interval of the article supported by the support portion from above, and the target interval can be switched such that the support portion and the pressing portion of the retracted position are separated in the vertical direction to allow The separation interval of the advancement and retreat movement of the aforementioned support portion.
根據此構成，藉著以間隔切換用驅動部將支撐部及按壓部的間隔切換成分開間隔，就可以在支撐部支撐的物品不會干涉到按壓部的情形下，使支撐部在退回位置及突出位置之間進退移動而在移載目的地之間移載物品。 According to this configuration, by the interval between the support portion and the pressing portion being switched by the interval switching drive unit, the support portion can be returned to the retracted position without the article supported by the support portion interfering with the pressing portion. The forward position moves between the protruding positions to transfer the items between the transfer destinations.
又，在使支撐有物品的支撐部位於退回位置的狀態下，因為按壓部位於物品的正上方，所以藉著以間隔切換用驅動部將支撐部及按壓部的間隔切換成按壓間隔，就可以使按壓部從上方按壓支撐部所支撐的物品。 Further, in a state where the support portion supporting the article is located at the retracted position, since the pressing portion is located directly above the article, the interval between the support portion and the pressing portion can be switched to the pressing interval by the interval switching drive portion. The pressing portion is pressed from above by the article supported by the support portion.
像這樣，藉由使支撐有物品的支撐部位於退回位置並且在將支撐部與按壓部的間隔做成按壓間隔的狀態下，使台車本體沿著行走路徑行走，就可以藉著使支撐部所支撐的物品受到按壓部按壓，而可以防止物品的上拋和傾倒， 並於以使物品支撐在支撐部上的狀態使台車本體行走時，可以藉由支撐部以穩定的狀態支撐物品。 In this manner, by supporting the supporting portion of the article at the retracted position and pressing the interval between the supporting portion and the pressing portion to make the trolley body travel along the traveling path, the supporting portion can be The supported items are pressed by the pressing portion to prevent the items from being thrown and dumped. When the trolley body is moved in a state in which the article is supported on the support portion, the article can be supported in a stable state by the support portion.
以下，針對本發明的較佳實施形態進行說明。 Hereinafter, preferred embodiments of the present invention will be described.
較理想的是，在本發明的物品搬送台車的實施形態中，還具備移載用昇降驅動部，在與前述移載目的地之間移載物品時，該移載用昇降驅動部可在前述突出位置使前述支撐部在承載高度以及比該承載高度還低的卸載高度之間昇降。 Preferably, in the embodiment of the article transporting trolley of the present invention, the loading/elevating driving unit is further provided, and when the article is transferred between the transfer destination and the transfer destination, the transfer lifting drive unit may be in the foregoing The protruding position causes the aforementioned support portion to rise and fall between the carrying height and the unloading height lower than the carrying height.
依據此構成，藉由從於移載目的地存有物品並且支撐部未支撐物品的狀態，到使卸載高度的支撐部從退回位置突出到突出位置後，使支撐部從卸載高度上昇至承載高度，之後，使支撐部從突出位置退回至退回位置，就可以藉支撐部承載移載目的地的物品。 According to this configuration, the support portion is raised from the unloading height to the carrying height by the state in which the article is stored at the transfer destination and the support portion does not support the article, until the support portion of the unloading height is protruded from the retracted position to the projected position. Then, the support portion is returned from the protruding position to the retracted position, and the article of the transfer destination can be carried by the support portion.
又，藉由從於移載目的地無物品存在並且支撐部支撐著物品的狀態，到使承載高度的支撐部從退回位置突出到突出位置後，使支撐部從承載高度下降至卸載高度，之後，使支撐部從突出位置退回至退回位置，就可以將支撐部所支撐的物品卸載至移載目的地。 Further, by the fact that no load is present at the transfer destination and the support portion supports the article, and the support portion of the load height is protruded from the retracted position to the protruding position, the support portion is lowered from the load height to the unloading height, after which the support portion is lowered from the load height to the unloading height. By retracting the support portion from the protruding position to the retracted position, the articles supported by the support portion can be unloaded to the transfer destination.
像這樣，因為可以藉著透過支撐部的進退移動及昇降移動而在與移載目的地之間移載物品，所以不必於移載目的地設置相對於支撐部將物品承載卸載的裝置，並可以謀求移載目的地的構成的精簡化。 In this way, since the article can be transferred between the transfer destination and the transfer destination by the advancement and retreat movement and the lifting movement through the support portion, it is not necessary to provide a device for unloading the article with respect to the support portion at the transfer destination, and The simplification of the composition of the transfer destination is sought.
較理想的是，在本發明的物品搬送台車的實施形態中，作為前述支撐部的高度，設定有比前述承載高度還 高且使前述對象間隔成為前述按壓間隔的按壓高度，並將前述承載高度設定成使前述對象間隔成為前述分開間隔的高度，且將前述移載用昇降驅動部構成為：可以將前述支撐部的高度變更成前述承載高度、前述卸載高度以及前述按壓高度的任一高度，而可兼用為前述間隔切換用驅動部。 Preferably, in the embodiment of the article transporting trolley of the present invention, the height of the support portion is set to be higher than the aforementioned load height. The height of the object is set to be the pressing height of the pressing interval, and the height of the load is set such that the target interval is the height of the separation interval, and the lifting/lowering driving portion for transfer is configured such that the supporting portion can be The height can be changed to any of the above-described load height, the unloading height, and the above-described pressing height, and can be used as the interval switching drive unit.
依據此構成，在已將支撐部昇降到承載高度的狀態下，是將支撐部與按壓部的間隔變成分開間隔，且在已將支撐部上昇至按壓高度的狀態下，是將支撐部與按壓部的間隔變成按壓間隔。因此，移載用昇降驅動部是藉由使支撐部在承載高度及按壓高度之間昇降，而可以使其發揮作為在分開間隔與按壓間隔之間切換支撐部與按壓部的間隔的間隔切換用驅動部的作用。 According to this configuration, in a state where the support portion has been raised and lowered to the load-bearing height, the interval between the support portion and the pressing portion is divided into intervals, and in a state where the support portion has been raised to the pressing height, the support portion and the pressing portion are pressed. The interval of the part becomes a pressing interval. Therefore, the lifting and lowering drive unit for shifting can be used to switch the interval between the support portion and the pressing portion by switching between the separation interval and the pressing interval by raising and lowering the support portion between the load height and the pressing height. The role of the drive unit.
據此，除了移載用昇降驅動部外，不必設置在分開間隔與按壓間隔之間切換支撐部與按壓部的間隔的專用驅動部，而能夠謀求使支撐部進退移動及昇降移動的構成的精簡化。 According to this, it is not necessary to provide a dedicated drive unit that switches the interval between the support portion and the pressing portion between the separation interval and the pressing interval, and it is not necessary to provide a configuration for reducing the movement of the support portion to move forward and backward and to move up and down. Chemical.
較理想的是，在本發明的物品搬送台車的實施形態中，前述按壓部具有彈性構件，該彈性構件是藉由隨著將前述對象間隔從前述分開間隔切換成前述按壓間隔以使前述按壓部接觸到前述支撐部所支撐的物品而產生彈性變形。 Preferably, in the embodiment of the article transporting trolley of the present invention, the pressing portion includes an elastic member that switches the pressing portion to the pressing interval from the separation interval to the pressing portion. The article supported by the aforementioned support portion is elastically deformed.
依據此構成，藉由將支撐部與按壓部的間隔從分開間隔切換成按壓間隔，而使按壓部從上方對支撐部所支 撐的物品形成接觸，並藉由這個接觸使按壓部的彈性構件產生彈性變形。 According to this configuration, the pressing portion is switched from the upper portion to the supporting portion by switching the interval between the supporting portion and the pressing portion from the separation interval to the pressing interval. The struts are brought into contact, and by this contact, the elastic members of the pressing portion are elastically deformed.
亦即，由於藉由在將支撐部與按壓部的間隔切換成按壓間隔時使彈性構件產生彈性變形，按壓部就可以藉由接觸物品而相對於物品相對地朝上方退避，所以可以將藉由使物品受到按壓部壓住之作法而會產生的按壓部及物品之破損防範於未然。 In other words, since the elastic member is elastically deformed when the interval between the support portion and the pressing portion is switched to the pressing interval, the pressing portion can be relatively retracted upward relative to the article by contacting the article, so that it can be Precautions against damage to the pressing portion and the article that may occur when the article is pressed by the pressing portion are prevented.
又，在將支撐部與按壓部的間隔切換成按壓間隔的狀態下，因為藉由彈性構件的賦勢力將按壓部按壓於物品上，所以可以藉由支撐部以穩定的狀態支撐物品。 Further, in a state where the interval between the support portion and the pressing portion is switched to the pressing interval, since the pressing portion is pressed against the article by the biasing force of the elastic member, the article can be supported by the supporting portion in a stable state.
較理想的是，在本發明的物品搬送台車的實施形態中，將前述台車本體構成為在受到配置在天花板側的行走軌道導引支撐的狀態下，沿著前述行走路徑行走自如。 In the embodiment of the article transporting vehicle of the present invention, the vehicle body is configured to be movable along the traveling path while being guided by the traveling rail disposed on the ceiling side.
依據此構成，因為台車本體受到配置在天花板側的行走軌道所導引支撐，所以相較於使台車本體被配置在地面上的行走軌道所導引支撐的情形，變成可以使台車本體在較高的高度處行走。像這樣使台車本體在較高的高度處行走時，藉由以按壓部按壓支撐部所支撐的物品以防止物品從支撐部落下，能夠避免物品掉落於在地面上進行作業的作業員及設置在地面上之機器上。 According to this configuration, since the trolley body is guided by the traveling rail disposed on the ceiling side, it becomes possible to make the trolley body higher than the case where the trolley body is guided by the traveling rail disposed on the ground. Walking at the height. When the trolley body is moved at a higher height as described above, by pressing the article supported by the support portion with the pressing portion to prevent the article from being lowered from the support tribe, it is possible to prevent the article from falling on the operator and setting up the work on the ground. On the machine on the ground.

作為搬送支撐體23的高度(變更目標的高度)，設定有卸載高度H1、高於該卸載高度H1的承載高度H2、及高於該承載高度H2的按壓高度H3。藉昇降用馬達25的驅動，形成為可將搬送支撐體23昇降移動至選自於卸載高度H1、承載高度H2、按壓高度H3中之任一高度。並形成為，在與 保管棚3之間移載物品W時，可使搬送支撐體23在從卸載高度H1至承載高度H2之間的移載用昇降範圍之間進行昇降移動，在使行走部17行走移動的行走時，可使搬送支撐體23上昇到脫離移載用昇降範圍而在上方的按壓高度H3處。再者，圖3及圖4所示為，搬送支撐體23位於卸載高度H1的狀態。圖5及圖6所示為，搬送支撐體23位於承載高度H2的狀態。又，圖7是，以實線表示搬送支撐體23位於按壓高度H3的狀態，並以假想線表示搬送支撐體23位於卸載高度H1及承載高度H2狀態。 As the height (the height of the change target) of the conveyance support 23, the unloading height H1, the bearing height H2 higher than the unloading height H1, and the pressing height H3 higher than the carrying height H2 are set. By the driving of the lift motor 25, the conveyance support body 23 can be moved up and down to any one selected from the unloading height H1, the load height H2, and the pressing height H3. And formed into When the articles W are transferred between the storage compartments 3, the conveyance support body 23 can be moved up and down between the lifting/lowering range between the unloading height H1 and the load-bearing height H2, and the traveling portion 17 is moved while walking. The conveyance support body 23 can be raised to the upper lift height H3 so as to be out of the transfer lifting range. In addition, FIG. 3 and FIG. 4 show the state in which the conveyance support body 23 is located in the unloading height H1. 5 and 6 show a state in which the conveyance support 23 is located at the load height H2. In addition, FIG. 7 is a state in which the conveyance support body 23 is located at the pressing height H3, and the conveyance support body 23 is in a state in which the conveyance support body 23 is located at the unloading height H1 and the load-bearing height H2.
於卸載高度H1的搬送支撐體23的頂面，會比保管支撐體10的頂面還位於下方，於承載高度H2的搬送支撐體23的頂面，會比保管支撐體10的頂面還位於上方。又，在搬送支撐體23位於退回位置的狀態中，使搬送支撐體23位於承載高度H2時，會使該搬送支撐體23所支撐的物品W的上端位於比按壓部15下端還下方的位置，且搬送支撐體23位於按壓高度H3時，會使按壓部15的接觸部34嵌入頂面凹部8，而使搬送支撐體23所支撐的物品W的上端位於比按壓部15下端還上方的位置。 The top surface of the conveyance support body 23 at the unloading height H1 is located below the top surface of the storage support body 10, and the top surface of the conveyance support body 23 at the load height H2 is located further than the top surface of the storage support body 10. Above. In the state where the conveyance support body 23 is located at the retracted position, when the conveyance support body 23 is positioned at the load height H2, the upper end of the article W supported by the conveyance support body 23 is located below the lower end of the pressing portion 15, When the conveyance support body 23 is located at the pressing height H3, the contact portion 34 of the pressing portion 15 is fitted into the top surface concave portion 8, and the upper end of the article W supported by the conveyance support body 23 is positioned above the lower end of the pressing portion 15.
因此，搬送支撐體23位於承載高度H2的位置時，並未使搬送支撐體23所支撐的物品W接觸到按壓部15，而能夠使搬送支撐體23在退回位置及突出位置之間進退移動。又，藉由在搬送支撐體23位於退回位置的狀態下，使搬送支撐體23從承載高度H2上昇至按壓高度H3，可以使按壓部15接觸搬送支撐體23所支撐的物品W以藉由按壓部15從上 方按壓物品W。 Therefore, when the conveyance support body 23 is located at the position of the load height H2, the article W supported by the conveyance support body 23 is not brought into contact with the pressing portion 15, and the conveyance support body 23 can be moved forward and backward between the retracted position and the projecting position. In addition, when the conveyance support body 23 is in the retracted position, the conveyance support body 23 is raised from the load-bearing height H2 to the pressing height H3, so that the pressing portion 15 can be brought into contact with the article W supported by the conveyance support body 23 by pressing. Part 15 from above The party presses the item W.
接下來，在藉由昇降用馬達25的驅動而使搬送支撐體23上昇至按壓高度H3的狀態下，可使在退回位置的搬送支撐體23與按壓部15沿上下方向接近，藉此，可將作為搬送支撐體23與按壓部15的上下方向上的間隔之對象間隔變成，按壓部15從上方按壓搬送支撐體23所支撐的物品W的按壓間隔。又，在藉由昇降用馬達25的驅動而使搬送支撐體23下降至承載高度H2的狀態下，可使在退回位置的搬送支撐體23及按壓部15沿上下方向分開，藉此，可將對象間隔變成容許搬送支撐體23的進退移動的分開間隔。 When the conveyance support body 23 is raised to the pressing height H3 by the driving of the lift motor 25, the conveyance support body 23 and the pressing portion 15 at the retracted position can be brought up and down in the vertical direction. The target interval between the conveyance support body 23 and the pressing portion 15 in the vertical direction is changed, and the pressing portion 15 presses the pressing interval of the article W supported by the conveyance support body 23 from above. In the state where the conveyance support 23 is lowered to the load height H2 by the driving of the lift motor 25, the conveyance support body 23 and the pressing portion 15 at the retracted position can be separated in the vertical direction, whereby The object interval becomes a divided interval that allows the forward and backward movement of the transport support body 23.
亦即，昇降用馬達25是兼作為，將退回位置的搬送支撐體23與按壓部15的上下方向上的間隔(對象間隔)，在按壓間隔與分開間隔之間進行切換的間隔切換用驅動部32用。 In other words, the lift motor 25 is a drive unit for switching between the pressurization interval and the separation interval, which is a distance between the transport support body 23 and the pressing portion 15 in the vertical direction (target interval). 32 used.

如圖8所示，接觸部34是構成為：從圖8(a)所示的基本位置往下方的移動會受到限制構件(圖中未示)所限制，而從該限制位置往上方的移動則，如圖8(b)所示，是抵抗彈簧35的彈力而移動。 As shown in Fig. 8, the contact portion 34 is configured such that the movement from the basic position shown in Fig. 8(a) downward is restricted by the restricting member (not shown), and the movement from the restricted position upward is performed. Then, as shown in FIG. 8(b), it moves against the elastic force of the spring 35.
按壓部15是，設置在位於退回位置的搬送支撐體23所支撐的物品W的正上方的位置，且接觸部34是位於，退回位置的搬送支撐體23所支撐的物品W中的頂面凹部8的正上方。亦即，由上下方向觀之，是將按壓部15設置在，相對於退回位置的搬送支撐體23所支撐的物品W，於上側 形成重複的位置，由上下方向觀之，是將接觸部34設置在，相對於退回位置的搬送支撐體23所支撐的物品W之頂面凹部8，於上側形成重複的位置。 The pressing portion 15 is provided at a position directly above the article W supported by the transport support 23 at the retracted position, and the contact portion 34 is a top concave portion of the article W supported by the transport support 23 at the retracted position. Just above 8th. That is, viewed from the vertical direction, the pressing portion 15 is provided on the article W supported by the transport support 23 with respect to the retracted position, and is on the upper side. The overlapping position is formed, and the contact portion 34 is provided at the top surface concave portion 8 of the article W supported by the conveyance support body 23 with respect to the retracted position, and is formed at a position overlapping on the upper side.
接觸部34是形成為，將越下方側變成越小徑之圓錐形狀之下端切除後的形狀。上面凹部8也是同樣地，凹入形成為，將越下方側變成小徑之圓錐形狀之下端切除後的形狀，且接觸部34是形成可與頂面凹部8嵌合的形狀。 The contact portion 34 is formed in a shape in which the lower end side of the conical shape having the smaller diameter is cut out.
